Ribosomal protein S20



Ribosomal protein S20 (RPS20) is one of the 22 proteins which belong to the small subunit of the bacterial ribosome. It is found only in bacteria and mitochondria. The images at the left and at the right correspond to one representative RPS20, i.e. the crystal structure of Ribosomal protein S20 from Thermus thermophilus (2zm6, chain T).
